A further bead reinforcing strip is formed radially inside the bead core, the further bead reinforcing strip extending axially over the entire axial length of the bead core and being radially outwardly folded back towards the two axial outer sides of the bead core. The further bead reinforcing strip having a first folded-back section extending up to a radial extension height from a vertex of the wheel rim and a second folded-back section up to a radial extension height from the vertex X of the wheel rim.
